✦ Synopsis


The concept of a diffusion coefficient dependent on a differential fractal dimension has been introduced into the theoretical treatment of diffusion-controlled reactions between particles lacking long-range interactions.

By this means Smoluchowski's theory can be extended to the more realistic case in which the mean free path of the reacting particles is finite. The theoretical calculations, corroborated by computer simulation experiments, show that reduction of the fractal dimension implies an effective reduction of the rate constant.
